CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to the following provisional application: U.S. Ser. No. 62/052,624, filed Sep. 19, 2014 entitled: A TWO PIECE STENCIL HOLDER FOR USE BY COOKIE DECORATORS AND HOBBYISTS TO SECURELY HOLD THE STENCIL THEY USE TO AIRBRUSH ONTO A COOKIE OR OTHER ITEM, the contents of which are incorporated herein by reference.

FIELD OF THE INVENTION

The invention relates to apparatus and utensils used to decorate food products and baked goods such as cookies, cupcakes, cakes and the like, and methods of using such apparatus and utensils.

BACKGROUND

Bakers, hobbyists and cookiers (one who bakes cookies) often desire to decorate their food products and baked goods such as cookies, cupcakes, cakes and other items. Often, this is done using stencils. Disadvantageously, stencils must be re-secured, re-aligned and re-steadied when moving from one cookie, baked item or other item, to another while airbrushing. This is a time consuming process, and often leads to errors such as overspray or misaligned designs. One method that bakers, hobbyists and cookiers use to overcome these problems is to use a stack of magnets on a cookie sheet to secure the stencil to the sheet and the stack of magnets. However, this is an inefficient and time consuming process as the stencil must be reset and realigned with every cookie, baked item or item being decorated. What is desired is an apparatus to hold the stencil taut and secure and which can be easily moved from one cookie, baked item or item, to the next with no additional set up time.

SUMMARY OF THE INVENTION

The present invention comprises a frame operable to hold a stencil taut and secure. The invention can be easily moved from one cookie, baked item or item to the next with minimal additional set up time. One embodiment of the frame is comprised of a bottom sub-frame having a first height, and a top sub-frame having a second height that is less than the first height, such that the bottom sub-frame accommodates one size of cookie when the bottom sub-frame is placed around the cookie and accommodates a thinner cookie when the frame is flipped 180 degrees along a lateral axis and the top sub-frame is placed around the cookie. The invention further is a two piece stencil holder for use by cookie decorators to secure a stencil when airbrushing a design onto a cookie. With the use of the frame, the stencil is held taut and secure and can be easily moved from one cookie to the next with no additional set up time.

DESCRIPTION OF THE INVENTION

The present invention comprises a frame having a bottom sub-frame and a top sub-frame with an opening formed by the interior sides thereof. By placing a stencil between the two sub-frames of the holder, which snap together with the use of, inter alia, magnets, the stencil is held secure. Preferably the stencil is held at the height of either ¼″ or ⅜″, depending on the position of the bottom sub-frame with respect to the food item being decorated. The stencil, as held by the frame (also referred to as a “holder”), can easily be lifted and moved from cookie to cookie or item to item while decorating without resetting the frame.

With the use of the bottom sub-frame and top sub-frame, the stencil is held taut and secure therein-between and can be easily moved from one item to the next with no additional set up time. One embodiment of the two-part frame is comprised of a bottom sub-frame having a first height, and a top sub-frame having a second height that is less than the first height, such that the bottom sub-frame accommodates one size of cookie when the bottom sub-frame is placed around the cookie and when the frame is flipped 180 degrees along a lateral axis, it accommodates a thinner cookie when the top sub-frame is placed around a cookie.

Without limiting the dimensions of the invention, an embodiment of the invention has dimensions and characteristics as follows:

1. Bottom sub-frame having ¼ inch height and four 5.5 inch sides joined as a square, made of plastic, the sides forming a 5 inch opening with cavities for magnets, such as neodyne magnets, to be secured therein with adhesives.

2. Top sub-frame having ⅜ inch height and four 5.5 inch sides joined as a square, made of plastic, the sides forming a 5 inch opening with cavities for magnets, such as neodyne magnets, to be secured therein with adhesives.

3. Four (4) neodyne magnets that are secured in each corner formed by the sides of the top sub-frame and four (4) neodyne magnets that are secured in each corner formed by the sides of the bottom side-frame, for a total of 8 magnets. The height of the sides disclosed are for illustration only and may be any height that is suitable for decorating a food or other item.

Once the magnets are secured into place with the use of a strong adhesive, the bottom sub-frame is held securely to the top sub-frame with the stencil therein-between. In this way, the stencil is held securely in place at the right height above the cookie to be airbrushed.

In an embodiment, the bottom sub-frame and top sub-frame are preferably fabricated from Acrylonitrile Butadiene Styrene (ABS) or Polylactic Acid (PLA) plastic or by injection molding plastic into desired frame shape. The magnets are then adhered into the bottom sub-frame and top sub-frame. Other material from which the bottom sub-frame and top sub-frame can be fabricated include, but are not limited to, Polyethylene terephthalate (PET or PETE), High density polyethylene (HDPE), Polyvinyl chloride (PVC), Low-density polyethylene (LDPE), or Polypropylene (PP).

In an embodiment, the user positions the bottom sub-frame with the exposed polarity of the magnets facing up and places a stencil on the top of the bottom sub-frame. The top sub-frame, with the exposed magnets facing downward, is then co-axially aligned with the bottom sub-frame. The magnetic force of the first polarity of the exposed magnets of the bottom sub-frame will attract, via the magnetic force of the second polarity of the exposed magnets, the exposed magnets of the top sub-frame. For example, the first polarity can be magnetic north and the second polarity can be magnetic south, or vice versa. The two sub-frames, when pulled together by the interacting magnetic forces, will hold the stencil taut between them. If a user is decorating a thin cookie or item, then the user will use, as a bottom sub-frame, a sub-frame having ⅜ inch sides. If the user is decorating a thicker cookie or item, then they will use as a bottom sub-frame, a sub-frame having ½ inch sides. The assembled frame is then placed over the item to be airbrushed.

In an alternative embodiment, in place of a bottom sub-frame, a bottom assembly of two parallel bars can be used to hold the stencil to the top sub-frame as further described herein. The present invention can also be used effectively by other crafting fields to hold stencils in place for decorating items placed within the opening of the bottom sub-frame.
